Title: Surface flaw detecting method
Inventor: KAZAMA AKIRA
IPC: B21C51/00
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a surface flaw detecting method stably detecting a surface flaw with good detectability even in a hot rolling process. SOLUTION: When light is radiated from a light projector 5 to a steel plate 1 positioned in the closest position to a final stand roll 2 of a finishing rolling machine, its reflected light is received by means of a line sensor camera 6 for image processing, and the surface flaw is detected. When a scale is formed on the steel plate 1, the scale becomes noise or covers the surface of the surface flaw and lowers flaw detection ability. Therefore, surface flaw detection is carried out while the scale is scarcely formed.
